Specification Vforming part of Letters Patent No. 45,2%?, dated November 29, 1864.

To all whom tracy concern Be it known that I, Tunes. WEAVER, of the city of Harrisburg and State of Pennsyl- Vania, have in vented new and useful Improve ments on an Adjustable School rfable and Seat Combined; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l is a perspective view. Fig. 2 is a front view. Fig. 3 is an end view, and Fig. 4 is a transverse section.

I construct the above table as follows: Two end boards are dovetailed into the lower side of the plank F', as shown in Fig. 2. These form supports for the front, bottom, and backboards constituting the bookcase, as shown in Figs. l and d, marked F F F F. lhe end boards form a recess at each end, as shown in Figs. 1 and 2, in which the standards R R are braced against them by rods at diierent heights through slots in the standards K K. rEhe rods have burs shaped into hooks L L L L. (Shown in Figs.l and2.) The standards branch into two legs, 'S and Y. The foot Y enters a shoe or staple, the other tits against the lath S S, as shown in Fig. l. Un the top of the plank F are the sections A D C of the adjustable leaf, as shown in Figs. l and 4, which are hinged together beneath, and section D is also hinged to the plank F. The ledge-B is attached to section C by screws through slots, and is adjusted by the button F, as shown in Figs. l and 4. rlhe ledge also buttons in at l), as shown in Fig. 3. The section A has the guide J, as shown in Fig. et. In the plank F are two slides, as shown in Figs. 2 and et. N is dovetailed from above, M from beneath the plank. N has a stem through a slot to move or stop it. M is notched to iinpinge on the staple U, and beveled to fit section C inclined. It is stopped by the knob coming in contact with the staple U. rlhe seat-board H (shown in Fig. 4) is hinged to the back G, which is hinged at Z. Thehaunchrod W revolves on bearings in the end of the book-Case, or may revolve on the rod L in the recess when only one arin is used for the seat. It forms the toggle-joint 0 with the curved sliding' arm X, through the slots Q Q in the back and seat boards, and the arm passes under the seat. The haunch W also rests against a notched brace or rubber on the back G when it is inclined. The ledge B of the leaf", as shown in Fig. 4, may be joined with section D, asitis with section G,thns omitting U for reiittin g old furniture on the plan of this table.

The operations of the leaf are, first, to form a plane writing-table, as shown in Fig. l, by extending section C and permitting the ledge B to. drop level with it, itbeing supported by the slide N, as shown in Fig. 2; second, to

form the inclined reading-table, as shown in Fig. 4, by drawing out the slide M, throwing up the ledge B, and buttoning it at E for a book-stop, and then the sections C D and A are fixed in place by drawing up the guide J 5 third, to fold section C, as shown in Fig. 3, push in the slides M and N, unbutton the ledge B, and slide it into the front to button in with section C at P. Y

The operations of the seat are, first, to form an inclined or recumbent seat, as shown in Fig. 4, by simply drawing out the seatboard p H and pressing' on it, the arm X and haunch XV arranging themselves to brace against the brace A on the back G, the arm X in the slot Q arrests the seat at the proper angle of inclination, and H moves on a hinge with the back G, which also moves on a hinge at Z, second, to form an erect seat by lifting the seat H, and pushing the haunch-rod NV out of the brace A' and causing it to fold in the recess behind the back, thus bringing the seat into the position as shown in Fig. l; third, to form a folded seat, as shown in Fig. 3, by lifting the seat-board H, permitting the arm X to fall through the slots Q Q, and to keep up the seat by its own weight.

The operations of the supports are, iirst, to form hat-racks in the end recesses on the hooks of the drawn burs L L L L, as shown in Figs. l and 2, second, to raise or lower the table by clamping or unclainping the burs L L L L on the rods running through the slots K K and through the table at diit'erent heights, as shown in Figs. 1 and 3; third, to fasten or unt'asten the desk, one foot entering a shoe, Z, as shown in Fig. 2, the other resting against the lath S S, shown in Fig. l; by lifting S the other may be slipped out of the staple.

I claiml. The standards R R, with their slots and rods K K at did'erent heights, the burs L L L L to clamp or unclamp them when adjusted, and the hat-racks formed by the hooked extremities of the buis, combined, arranged, and operated as herein shown and described.

2. The combination and arrangement ofthe compound adjustable leaf A C D, hinged together underneath the sections, section D hinged to the plank F', the guide J, the slides M and N, the niode of inserting them into the plank F', the staple U, the adjusta ble ledge B, with its slots, the button E operating substantially in the manner as and for the purposes herein set forth.

3. The combination and arrangement of the haunch-rod W, `the toggle-joint O, the curved arm X, the slots Q Qin seat and back, the notched brace or rubber A', the hinges Z, substantially as and for the purposes herein set forth.

4:. The combination of the adjustable led ge B with sections D and A,for the purpose herein described.
